The B-52 was carrying four hydrogen bombs more powerful than those
dropped on Hiroshima and Nagasaki. Two were recovered intact from the
sea but the others leaked radiation into the surrounding countryside
when their plutonium-filled detonators went off, strewing 3kg of highly
radioactive plutonium 239 around Palomares.

Secretary
Kerry just signed a deal with Spain to bring plutonium contaminated
soil and waste from Spain to the US. The contamination in Spain resulted
from a US B52 bomber colliding during refueling in 1966 and dropping
four nuclear bombs on Spain. The bombs did not detonate, but the
plutonium waste is still widespread. It is past time to abolish nuclear
weapons worldwide. 116 countries have already signed the pledge.

The Palomares clean-up deal is seen by many as a sweetener in exchange
for Spain agreeing to Washington ramping up its military presence in the
country. The number of marine personnel at the base in Morón in
southern Spain is to be increased from 850 to 2,200, and to 3,000 in the
event of a crisis.

There were 2 crashes actually, and just 2 years apart. In each case the local population participated in the cleanup, but had no protective gear and were not told about the risks. US military knew of the risks, and just "pretended" they didn't exist. A truly disgusting example of the cold war and cold sociopaths running our country. Real story in link below.

The accident occurred at the height of the Cold War when it was U.S.
policy to keep nuclear-armed warplanes in the air constantly near the
Soviet border.

The statement said that immediately following the accident both
countries set about securing the area, removing contaminated soil and
decontaminating the land. It said that they have since been monitoring
and analyzing contamination levels

Its the lack of cleanup. Not the fact that we have nuclear weapons. But the cold war insanity of keeping planes with nukes bombs in the air CONTINUOUSLY during the 60's was just asking for an accident.

So could you identify which, among governments which have the nuclear weapons, qualify in your mind as rational. And while you're at it, perhaps you could clarify your position by defining your use of the word 'rational' for us. Just curious.
